To It whom it may concern.-

Be it known that I, GEORGE WV. WILEY, a citizen of the United States,residing at Estherville, in the county of Emmet, State of Iowa, haveinvented certain new and useful Improvements in Draft-Equalizers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to draft-equalizers, and has for its object toprovide a device of this kind with which the draft of several horsesattached to a vehicle may be equalized and which will include a novelarrangement of parts permitting of the adjustment of the equalizer tosuit different conditions.

Other objects and advantages will be apparent from the followingspecification, which describes an embodiment of the present invention. I

In the drawings forming a portion of this specification and in whichlike characters of reference indicate similar parts in the severalviews, Figure 1 is a top plan view of the present equalizer. Fig. 2 isabottom view. Fig. 3 is a longitudinal section. Fig. 4 is a detailsection on line 4 4 of Fig. 2. Fig. 5 is a top plan view of a modifiedform of the invention.

Referring now to the drawings, there is shown a draft-pole 6 of avehicle, to the under side of which there is secured alongitudinally-extending casting 7. In the rearward portion of thiscasting there is a transverselyextending passage 8, and projectinglaterally from the casting in an opposite direction there are pairs ofhorizontally-extending wings 9 9 and 10 10, these wings extendingoutwardly above and below the passage 8. Slidably engaged in the passage8 there is a transverse member 11, having a longitudinally-extendingseries of perforations 12 therein, and the wings of each pair areprovided with registering perforations 13, adapted for interchangeableregistration with the perforations 12, the casting itself being providedwith an opening 14, communicating with its under face and with thepassage 8 and registering with a threaded recess 15 in the upper wall ofthe passage for the reception of a-pin 16, this pin having a threadedend which enters the threaded recess, and this pin is adapted forengagement in the perforations 12 interchangeably for pivotal movementof the member 11 thereupon, and it will thus be apparent that the membermay be moved longitudinally through the passage 8, the pin 16 beingshifted to different perforations of the member to adjust this portionof the equalizer, and it will be understood that the pin may be removedfrom the perforations 14 and the recess 15 and engaged in theregistering perforations of one of the pairs of cars and in one of theperforations 12 to shift the pivotpoint of the member 11 to one side ofthe tongue 6, the dimension of the passage 8 longitudinally of thetongue being such as to permit of lateral movement of the member 11therewithin.

When it is desired to hold the member 11 against pivotal movement, anadditional pin may be disposed in one of the registering pairs ofperforations and in one of the perforations 12, which will produce thedesired result, as will be readily understood.

Brackets 17 and 18 are secured to the under face of the draft-pole 6 andextend laterally beyond one side thereof, the bracket 17 being locatedforwardly of the bracket 18, and pivoted at its inner end in the bracket17 there is a laterally-extending horizontal arm 19, having awhiffletree 20 connected thereto at its forward side.

An arm 21 is pivoted in the bracket 18 at one end and extends oppositelyto the arm 19 and beneath the draft-pole 6, a guide 22 for the arm 21being secured to the under face of the draft-pole. The arm 21 has awhiffietree 23 connected thereto at its forward side, and a link 24 ispivotally connected with the arm 21 and with the portion of the member11 lying at the same side of the draft-pole, a rod 25 being similarlyconnected with the opposite end portion of the member 11 and with thearm 19, and these rods 24 and 25 are shiftable longitudinally of theelements to which they areconnected to vary the leverage, the rodshaving angular ends 26, removably engaged in perforations 19 and 21 ofthe arms 19 and 21, respectively, and also in the perforations 12 of themember 11.

In Fig. 5 there is shown a modified form of the invention, in which thedraft-pole 6 is replaced by a short supporting-beam A, to which the armsand member are connected in the manner described and having a clevis Bat its rearward end, this form of the invention being especially adaptedfor use in connection.

with plows.

What is claimed is- 1. In a draft-equalizer the combination with asupport, of a transverse member pivotally connected with the support,said member being shiftable longitudinally, a laterally-extending armpivoted at one side of the support, connections between said arm and oneend of the member, a second arm pivotally connected with the support atthe same side as the first-named arm and extending beyond the oppositeside of the support, connections between the second arm and the otherend of the member, said connections being arranged for movement of thetwo arms and the member simultaneously and being shiftablelongitudinally of the arms and member, and attaching devices carried bythe arms.

2. In adraft-equalizer the combination with a support, of a castingsecured to the support and having a passage extending transversely ofthe support, a member disposed in the passage and having a longitudinalseries of perforations therein, oppositely-extending pairs of lateralwings carried by the casting and lying above and below the member, thewings of each pair having registering perforations therein, a pinremovably engaged in the casting and in one of the perforations of themember, the perforations of the wings being adapted to receive a pinengaged in a perforation of the member, oppositely-extending armspivoted to the support and connections between the arms and the memberfor simultaneous movement thereof, said arms being adapted for theattachment of draft-animals thereto.

3. In a draft-equalizer the combination with a support, of a castingsecured to the support, a transversely-extending member pivoted in thesupport and arranged for longitudinal adjustment, means for holding themember against pivotal movement, laterally-extending brackets carried bythe support at one side thereof, oppositely extending lateral armspivoted in the brackets, one of said arms extending beneath the supportand beyond the opposite side thereof, a guide for said arm andconnections between the arms and the member at opposite sides of thesupport, said connections being shiftable longitudinally of the arms andmember.

In testimony whereof I afiEiX my signature in presence of two witnesses.
